Hello,
A month, or so back I managed to build a new system based the Intel Z87 Express Chipset.
CPU: Intel Core i7-4770K
MB: ASUS Maximus VI Hero - Intel Z87 Express Chipset
RAM: Kingston HyperX Genesis - 16GB Kit (4x4GB) - DDR3 1600MHz CL9 Intel XMP, Part Number: KHX1600C9D3K4/16GX, Specs: DDR3, 1600MHz, CL9, 1.65V, Unbuffered, 1333MHz, 9-9-9, 1.50V, Profile 1: 1600MHz, 9-9-9, 1.65V, (

Video Card: ASUS GeForce GTX 780 DirectCU II
SSD: 2x Kingston HyperX 3K 120GB(SH103S3/120G) (not used in RAID) - SATA3
HDD: 1x WD VelociRaptor 500GB(WD5000HHTZ) – SATA3
PSU: Seasonic Platinum-1000 (SS-1000XP)
Case: Thermaltake Chaser A71
CPU Cooling: Noctua NH-D14
Case Cooling: Front (intake) 200mm fan (600rpm), Rear (exhaust) 120mm fan (1000rpm), Top (exhaust) 200mm fan (600rpm), Side (intake) 200mm fan (600rpm)
Peripherals: SteelSeries Apex Keyboard, SteelSeries Sensei MLG Mouse, Apple Cinema Display 21”
OS: Windows 7 64bit Home Premium
After searching the web for some answers regarding different matters related to my system I can't say I found a final answer to my questions, and I thought I may ask here. So...
1. The RAM. These are from my previous system, and since this RAM kit appeared in ASUS Motherboard Manual and DRAM Qualified Vendors List at 1600MHZ 9-9-9 1.65V, also on Intel Extreme Memory Profiles that was tested with 4770k at 1600MHZ 9-9-9 1.65V and Z87 Chipset (the DIMM module KHX1600C9D3/4GX in that is contained in the above kit KHX1600C9D3K4/16GX), Windows 7 64bit Home Premium does only recognize 16GB RAM, these are low profile so Noctua NH-D14 can fit, and because RAM is much expensive now I choose to keep and use them with XMP profile 1600Mhz 9-9-9-27 1.65V.
Links to check the RAM where I mentioned:
http://www.intel.com/content/www/us/en/gaming/xmp-for-core-processors.htmlhttp://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/MAXIMUS-VI-HERO/M6H_DRAM_QVL_0703.pdfAlso I saw the 4770k memory voltage spec are: 1.50V, <= 1.65V XMP (understood less or equal), 1.35V DDR3L so I thought this RAM Kit is ok.
I put all components together set in UEFI only XMP Profile to 1600Mhz 9-9-9-27 1.65V Installed Windows, benchmarks, tests, played some games for short time like Battlefield 3, Crysis 2, SWTOR... all was OK... no BSOD, hang, freeze, or any other problem. Tested the Ram with Memtest86 - 1 Cycle - no errors. Doing this noticed in ASUS manual a note on Ram that is recommended Ram voltage less than 1.65V, here wasn't less or equal to 1.65V. So I searched on google for people opinions and started to get worry about not damage the IMC/CPU with 1.65V. Most of the people comments were NOOO WAY 1.65V, only a few that run on 1.60V, 1.65V or even 1.71V. So I put back the RAM on default 1333MHZ 9-9-9-21 1.50V.
a) Long story, short in my system configuration, the above RAM with XMP profile set in UEFI 1600Mhz 9-9-9-27 1.65V, it will damage or not the IMC/CPU – CPU on default settings? Should I use it in XMP configuration? I hope for an answer from someone who really know about what is talking about.
b) If I set the XMP profile in UEFI 1600Mhz 9-9-9-27 1.65V, save and enter back in UEFi the DRAM voltage is around 1.668 for example. This is ok?
c) When setting the XMP in UEFI the profile is like this written: 1600Mhz 9-9-9-27 1.65V-1.20V. The 1.20V at the end what is it?
d) If I use the XMP 1.65V on RAM can I think about overclocking the CPU?
Attached ASUS SPD Information:
2. Used the computer for a while then went Start → Shutdown... shut down screen, then display went all black q-code 05 on motherboard, fans, lights in case running. Couldn't reproduce this after.
What I've changed before I get this:
- Updated to latest BIOS 0804 a couple of days ago with the Flashback button from the rear motherboard panel from a USB stick using the marked port for this function.
- Added WD VelociRaptor 500GB(WD5000HHTZ) – SATA3 on Intel SATA port 04. OS is installed on one of the SSDs port 01
- UEFI settings: disabled fan settings to auto adjust, enabled fast boot and done some settings in fast boot section. Hardware fast boot was on disabled.
Any idea about this q-code? Didn't found any 05 q-code in motherboard q-codes list from the motherboard's manual.
3. Never had a 10000rpm HDD. Have nothing on it, and didn't accessed but noticed that from 1,2sec to 1,2 sec it makes a reading/writing sound like any other HDD and of course HDD lights up.
This is a normal behavior?
4. Random. When prompt to enter UEFI Press DEL to enter UEFI, mouse light turn of and mouse is not working in UEFI. Exit UEFI, Windows loaded, mouse not working either until I plug out the mouse and plug back in the USB port. This also first happened after the updated yo 0804 UEFI.
Note: Didn't blame the UEFI update I just mention what was changed when some of the above happene%%d. And in this period I haven't installed any new software beside the Regular Windows Updates when were available. Also mouse and keyboard are plugged in the 2 USB ports near the PS2 connector in the rear motherboard panel.
